Abstract

Provided is an ultra-wideband differential antenna with a notch characteristic, comprising a dielectric substrate, a ground plate located on a lower surface of the dielectric substrate, and a feeding layer located on an upper surface of the dielectric substrate. The feeding layer comprises two radiation units arranged in a bilaterally symmetrical manner. The radiation unit comprises a micro-strip feeder and a radiation patch. The micro-strip feeder is connected to the radiation patch. The ground plate comprises four chamfers located at the edge of the ground plate and in radial symmetry, a circular gap located in the middle of the ground plate, and two C-shaped metal belts arranged in a bilaterally symmetrical manner and located in the circular gap. The C-shaped metal belt is parallel to the edge of the circular gap, and there is a space between the C-shaped metal belt and the edge of the circular gap. The ultra-wideband differential antenna with a notch characteristic of the present invention achieves the miniaturization of same, and achieves a good notch function. Moreover, the radiation characteristic of the antenna at a high frequency band is optimized and improved, and the gain of the antenna at a high frequency is also improved.

Description

technical field [0001] The invention relates to the technical field of microwave communication, in particular to an ultra-wideband differential antenna with notch characteristics. Background technique [0002] Since the Federal Communications Commission announced the use of the 3.1-10.6GHz frequency band in the commercial field in 2002, ultra-wideband (UWB) communication systems with high data transmission rates, low cost, low power consumption, and strong anti-interference capabilities have developed rapidly. UWB antennas It has become a research hotspot of international scholars in recent years. However, within the coverage of ultra-wideband, some frequency bands have already been occupied, such as WiMAX (3.4-3.6 GHz), and WLAN (5.15-5.35 GHz) and (5.725-5.825 GHz). Therefore, the UWB antenna may interfere with the existing communication network during operation. [0003] Therefore, there is a need for an ultra-wideband differential antenna with notch characteristics tha...
